    <subfield code="a">&lt;p&gt;Currently, composite materials are becoming popular in the automotive and aeronautics&lt;br&gt;
industries because of their high strength-to-weight ratio compared to traditional engineering&lt;br&gt;
materials. Bio-fiber composites are among natural fiber composites with carbon negative, bio&lt;br&gt;
degradable and renewable capabilities. In this research, the main aim was to investigate the&lt;br&gt;
mechanical and water-absorbing properties of sisal and sugarcane bagasse hybrid fiber&lt;br&gt;
polyester composite. During the manufacturing methods, extracting sisal fiber from the sisal&lt;br&gt;
plant, cutting of sugarcane bagasse fiber into chopped form and chemical treatment of the fibers&lt;br&gt;
with 5% NaOH solution for 24 hours were pre manufacturing process. Measuring the weight&lt;br&gt;
of these two constituent fibers in three different proportions as 10%Wt of sisal fiber with&lt;br&gt;
20%Wt of sugarcane bagasse fiber (10S/20B), 15%Wt of sisal fiber with 15%Wt of sugarcane&lt;br&gt;
bagasse fiber (15S/15B) and 20%Wt of sisal fiber with 10%Wt of sugarcane bagasse fiber (the&lt;br&gt;
20S/10B) to be manufactured in three different layering sequences of Sisal-Bagasse-Sisal&lt;br&gt;
(SBS), Uniform mixing (UNF) and Bagasse-Sisal-Bagasse (BSB) at two different curing&lt;br&gt;
temperatures (25&amp;deg;C and 60&amp;deg;C) was the next process. Hand layup these metered fibers with&lt;br&gt;
polyester resin and pressing with a hydraulic press machine in the confined steel molds was&lt;br&gt;
the second process. The manufactured samples were cut into the appropriate dimensions based&lt;br&gt;
on ASTM standards of 2017 for each test after they have been cured enough&lt;/p&gt;</subfield>
